Hi everyone,
Long time reader, first time poster. Have always found this forum useful to diagnose issues I face with my Mk1 ZS EV but I've come across something I'm stumped on. I purchased my car new (had been sitting in the dealer's yard for some time) last year, it is a 2021 MG ZS EV Mk1 (Standard range is all we have in Australia).
For the last 9 or so months I have gotten by using the supplied 10A granny charger, but about 6 months ago I noticed an issue with it where the car would stop charging when nowhere near full, and the granny would flash both the charge and power lights as if the charge had completed. At that time, I found I could get the car to charge again if I plugged it and replugged it in, but it would only charge for about 5 to 10 minutes before doing the exact same thing.
This occurred over any SoC and was no more frequent at lower SoCs than higher.
I initially blamed the granny charger, naively. The issue was so intermittent though that by the time I was sufficiently frustrated to report the issue to my local dealer, the problem would disappear again and not reappear for weeks.
In frustration one day, I bought a Level 2 charger/EVSE online, and had it installed last week. It worked fine initially, but then just like clockwork, the issue has returned. I can confirm it is not the wall charger as it's occurring on the granny too (please see video).
All I get is the 'connected but not charging' and the car will whirr the locking mechanism every minute or so. The only 'fix' seems to be to unplug it for a while and try again in a few hours, in hope it works.
Today when it occurred, it had charged fro 40 minutes on the wall charger before suddenly refusing any further and displaying the 'connected but not charging'.
I have now asked my dealer to look into it and I'm awaiting a call back, but considering the lack of knowledge around EVs and the fact I cannot replicate the issue on demand leaves me thinking that the dealer is going to tell me nothing is wrong, and send me home.
FYI - there is a Level 2 AC charger (BYO Cable) at a shopping centre that this consistently occurs at, too.
Any thoughts? Faulty onboard charger?
Thanks
